Summary
Urinary stone disease in cross-fused renal ectopia is rare. Ureteroscopic stone extraction via retrograde approach is a safe and effective treatment for ureteral stones in this rare condition.
Area of Science:
- Urology
- Nephrology
Background:
- Urinary stone disease in cross-fused renal ectopia presents unique anatomical challenges.
- Limited literature exists on effective treatment modalities for this rare condition.
Observation:
- A case of a 69-year-old woman with an obstructing ureteral stone in cross-fused renal ectopia was managed.
- The patient had a stone composed of 100% calcium oxalate monohydrate and low urine volume.
Findings:
- Ureteroscopic stone extraction was successfully performed using a retrograde approach.
- A ureteral access sheath, holmium laser, and Nitonol basket facilitated stone fragmentation and removal.
Implications:
- This case demonstrates that a retrograde approach with an access sheath is a safe and effective option for treating ureteral stones in cross-fused renal ectopia.
- Tailored modifications to the technique based on individual anatomy are crucial for successful outcomes.

01:30Types of Building Stone
440
Building stones, essential materials for construction, are extracted from natural rock deposits and processed into specific forms and dimensions suitable for various building applications. These stones are broadly classified into three types based on their geological formation: igneous, sedimentary, and metamorphic.
Igneous rocks are formed from the solidification of magma or lava. An example is granite, known for its durability and resistance to weathering, making it ideal for parts of...

01:26Reclosers and Fuses
476
Automatic circuit reclosers enhance the protection of distribution circuits by interrupting and auto-reclosing an AC circuit according to a preset sequence. They effectively manage temporary faults on overhead distribution lines, often caused by tree limbs or wildlife, by briefly disrupting service to improve overall reliability. However, contact with reclosers or energized broken conductors on the ground can pose serious hazards.

01:15Quarrying of Stone
580
Quarrying is the process of extracting stone from a quarry, where specialized techniques are employed to remove large blocks of stone safely and efficiently. This process can involve controlled explosions or more precision-oriented methods such as cutting and drilling.
One common method involves using a diamond belt saw to cut large blocks from the quarry face. These blocks can be about 50 feet long and 12 feet high. After the initial vertical cut, drilling is performed at the base of the...

01:29Stone Masonry
464
Stone masonry is a construction technique that uses individual stones to build structures and can be categorized into two main types: rubble and ashlar. Rubble masonry uses uneven, naturally shaped stones such as river rocks or fragments from quarries. This method often requires the mason to select and possibly shape each stone to fit the designated space, ensuring a proper build, even with irregular stone sizes and shapes. Ashlar masonry, on the other hand, employs uniformly cut stones that...

01:34Crossing Over
171.9K
Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...

01:30Crossing Over
6.5K
Crossing over is the exchange of genetic information between homologous chromosomes during prophase I of meiosis I. Genetic recombination gives rise to allelic diversity in the newly formed daughter cells. In humans, crossing over produces genetically distinct haploid egg and sperm cells that undergo fertilization to produce unique offspring. Before cell division starts, the germ cell’s chromosome(s) undergo duplication in the S phase of the cell cycle. As the cells enter prophase I,...
